2R: Efficiently Isolating Cold Pages in Flash Storages
Summary: 2R proposes a two-region FTL isolating cold pages in a dedicated region to cut relocations and amplification. Its FIFO-based 2R-FIFO reduces false cold pages; in OLTP runs it halves write amplification vs 1R-Greedy and yields up to 4× near full capacity. (summarized by gpt-5-nano on Feb 09 2026)
